Solve the system using the elimination method. 3x-2y=15 x+_y=0

mestny [16]

Answer:

x = 3, y = -3

Step-by-step explanation:

3x - 2y = 15 (eq 1)

x + y = 0 (eq 2)

(eq 2) x 2

2x + 2y = 0 (eq 3)

(eq 1) + (eq 3)

5x = 15

x = 3

SUB x=3 into (eq 2)

3 + y = 0

y = -3

(5,12)and (2,6) rate of change? Initial value? HURRY i NEED this done.

Otrada [13]

Answer:

Part 1) The rate of change is $2$

Part 2) The initial value is $2$

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or rate of change

b is the y-intercept or initial value

step 1

Find the slope or rate of change

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have the points

(5,12)and (2,6)

substitute the values in the formula

$m=\frac{6-12}{2-5}$

$m=\frac{-6}{-3}$

$m=2$

therefore

The rate of change is $2$

step 2

Find the initial value

we have

$m=2$

$point\ (2,6)$

substitute in the equation $y=mx+b$

$6=2(2)+b$

solve for b

$6=4+b$

$b=2$ ---> initial value

The linear equation is equal to

$y=2x+2$

The y-intercept or initial value is 2

Store a sells 12 bottles of water for 3.36 store b sells 24 bottles of water for 6.00 How much more Willa customer pay for 48 bo

Nataly_w [17]

Answer:

$1.44

Step-by-step explanation:

Store A:

12 bottles of water for $3.36

Then

48 bottles of water for $\$3.36\cdot 4=\$13.44$ (48 bottles is 4 times greater than 12 bottles)

Store B:

24 bottles of water for $6.00

Then

48 bottles of water for $\$6.00\cdot 2=\$12$ (48 bottles is twice greater than 24 bottles)

Difference:

$\$13.44-\$12=\$1.44$
